Another object is to provide a novel closure plate carried by the sashto coact with the upper edge of the screen, which plate is movablymounted so that it will permit closing of the sash without requiring itsdetachment therefrom.

A third object is to provide a novel spring control and tensioning meansfor the screen.

Additional objects and advantages will become apparent from aconsideration of the description following taken in connection withaccompanying drawings illustrating an operative embodiment.

In said drawings 2- Figure 1 is a view in front elevation showing thescreen in operative position applied to a window frame fragmentarilyillustrated;

Figure 2 is a vertical sectional view on the line 22 of Figure 1;

Figure 3 is an enlarged elevation of the device alone, partly brokenaway and in section to disclose details;

Figure 4 is a sectional view on the line ll of Figure 3;

Figure 5. is a fragmentary vertical sectional view through the windowframe showing the lower sash in closed position;

Serial No. 623,266.

Figure 8 is a sectional view taken on the plane indicated by the line8-8 of Figure 3.

Like reference characters designate like or similar parts in thediflerent views.

To facilitate an understanding of the invention, a window has beenconventionally and fragmentarily shown of which A designates the sill, Bthe stiles rising therefrom, C the stop strips fastened to said stiles,D a vertically slidable lower sash and E the stool.

In reducing the invention to practice, a suitable casing, preferablymetallic is provided as at 10 and adapted for vertical disposition atone side of the window in contact with the stile at said side and withits ends engaging the sill A and lower edge of the sash D, respectively.

Casing 10 consists of a hollow shell 11 provided with a vertical slot oropening 12 at one side thereof through which a. flexible metallic orother screen 13 travels. Adjacent the slot 12, the shell 11 has asubstantially straight wall 14 which is adapted for intimate contactagainst the inner edge of the stool E. At the ends of the shell, caps 15and 16 are provided and at least one of them is detachable or removableand for instance the cap 16. To this end, cap 16 has 21 depending rim 17to encircle the exterior of shell 11 and which is provided with inwardlypressed lugs at 18 adapted to snap into openings 19 provided in theshell. The cap 16 being of metal, has certain resiliency which permitsyielding or snapping of the lugs 18. Each cap 15 and 16 has an inward-1y extending sleeve or trunnion 20 and 21, respectively, integral withthem which are exteriorly cylindrical or round and extend through endplates 22 and 23 of a roller 24 which is journaled or rotatably mountedthereby. The screen 13 at its inner end as at 25 is fastened to theroller.

A spindle 26 is disposed longitudinally of the roller in a recess 27,with the inner end of the spindle which is round, located in a recess 28in extension of recess 27 and which is of such size as to permit thespindle to slide therein longitudinally of the roller. The outer end ofspindle 26 is square or noncircular as at 29 and normally occupies asimilarly shaped non-circular bore 30 provided through the sleeve 21. Ashoulder 31 is provided on the spindle to engage the inner end of sleeve21 and thus prevent outward displacement of the spindle. Within thereofto vary the tension of said spring, and said spring serving to normallymaintain said spindle in engagement With said means.

2. A roller device of the class described including a casing having anend provided With an inwardly extending trunnion, a roller Within thecasing journaled on the trunnion, said trunnion having a square slot, aspindle within the roller having a square portion engaging said slot anda shoulder engaging said trunnion, a winding spring for the rollersecured to the roller and to the spindle, said spindle being slidable todisengage said slot whereby the spindle may be turned to vary thetension of said spring, said spindle being round at its inner end, theroller having a recess to journal said inner end and elongated toprovide clearance for sliding movement of the spindle, and said springnormally maintaining said square portion in said recess.

3. A roller Window screen including a casing provided at one end with anangular opening, a roller journaled Within the casing, a spindle mountedWithin the roller for endwise and rotary movements with respect theretoand having an angular outer end entering said opening, and a spring connected to the spindle and roller and yieldingly retaining the angularend of the spindie within said opening.

In testimony whereof I aiiix my signature in presence of two witnesses.
